This invention relates to automat-ic `train means pipe connecters and particularly `to for supporting the coupling head. l

It is the object of the invention yto provide a support for the coupling head which will readily permit movement of the head in all directions, which is simple in construe-1 tion', which has comparatively few parts and which can be easily manufactured andl as sembled. Another. object-is t` provide an' improved` means for securing the coupling head in different positions relative to the` coupler headef the car. Other objects and advantages of the"` improved construction:

will be iapparent to those skilled in the art.

The invention'is illustrated in the accom-v panying drawings forming l specification and in which:

'Figure 1 is a longitudinal vertical secf tionalview partly in elevationshowing the improved construction;

Figure 2'is a horizontal longitudinal section of tlie;construction certain parts'be-v ing omitted; l

Figure 3 is a transverse vertical section?.-

al viewI on the line 3 3 of Figure 1;

Figure 4 is a detailed view showing one of its upper end the bracket 11 is providedV with spaced lportionsor ears 11a which*y are adapted to lie upon opposite vsides of the lug 10, this lug being provided'with suit-V l able holes through whichfastening bolts 12 are inserted for securing the bracket-to the g Y g Each ofthe earsllaof thebra'cket 11' is provided with an: elongated yopening in.y

which a reversible liller block 13 is mounted,

' each of these tiller'blocks being-provided the lug 10. The openings 14 Vof the ller. l blocks 13 arey offset orlunsymmetrically posi-VV tioned withjreference to the center of the blocks, that is, they are so arran'ged'that when these blocks are reversedV orv turned end to end the bracketll' will be secured in 'difeI part of 'thisl trunnion`19 on each side-0f the seat 18 or on ferentl positions. i The vfiller blocks thus constitute v,means by which the bracket may` be` adjusted.longitudinally of the car sorthat l the positionpfthe coupling head supported by the bracket may be varied lwithreference` tothe -face ofthe car coupler. f

Near its lower end the'bracketll isshaped toform" a cylindrical'bearing portion or member 15 beneath which thereV is provided a'head ortenlarged'portion 16for a purposel hereinafter` described.'V A pivot? block 1? is arranged to engage the .bearing portion 15 l of theY bracket, thisblock being provided intermediate its ends :with .a curved 'seat 18"v vwhichbears against thevl curved lfronty portion of the cylindrical bearing member 15. The pivot block 317 is'al'so'provided with a each sideof tlie'bearing' portion 15 of theA bracket. i f

j A xstem 20,-. extends yrearwardly of the bracket y.11,'xthe Afront end` of which is .prof

vided with spacedportions QO'Wshapedto-V engage the trunnions 19 of th'epivotblock"y 17. yThe portions 2Oa of the stem are prefer-E ably made in the shape of hooks whichfi't' over thetrunnions =19. ."At kits rear end the stem 2O isthreaded and uponV such threaded' portion -anV abutment21is adjustalolyA mounted.

. .y v The coupling `head 225 of Lmyimpr'o'ved construction lmaybe'lof the ordinary type` provided with* wings 22a lfor cooperating with the wings of a mating head. To support` the head infront of the'bracketth'ere` is provideda supportingmember 23' whichy is's'ecuredto'the head in anysuitable man' ner, preferablyl by being-attached' to'j the usualk conduit 22b which; extends 'l'atveallyfl fromfthe rear portion of thevhead 'andvvhich` is adaptedto receive a train pipe hose. The supporting member 23l is 'preferably formed of spaced arms 23a which extend rearwardlyl from`thehe`ad22-to therear of the Abracket and totheV `'rear portion of isaid"arms"23"" there kis securedV a flange. or projection-24 whichv isadapted to contact withthe rear face ofthe bracket,y such :flange or projection' 24 preferably being! formed integrat vwithsaidfarms 23a. :Therear face of the flange or projection 24 is provided with suitable seat-25 and a coileds'pring 26'is arv ranged between Vsaid seat;v and the abutment 21heretofore'mentioned on'the stem '20,' f. l

The spring 26 acts to hold the flange 24 ofY the .supporting member 23 yieldingly against the rear `face of the bracket 'so thatv thehead 22 is maintained in proper position f, tocooperate with the mating head Von another car. The tension ofthespring 26 may be varied by adjustn'ient. of the Vabutment 21 on the stem 20. By reason of the .pivotal engagement between thel stem and the trunnions of the pivotblock 17 and-the pivotal engagement of the ypivotrblock on the bearingportion lof the bracket itis apparent that the coupling'. head will be free to move in all directionsto .accommodate 'the relative f movement betweenY cars in passing varound Y curves or over uneven track.v

The arms 23 `of the supporting member .3 have vtheir inner surfaces arranged in yclose j 'proximity to theen'dsl of the trunnions 19 so that rotation of the coupling head on its V-longitu'dinal axis is prevented and thepivot block 17is prevented from downward movementby the head 16 on the lower end of the bracket.

Y V'Variouschanges mayl of course be made in the details of the foregoing construction withoutV departingfrom the scope of the,n'

ventionwhich it should be understood is not limited to such specific details. i
